The zoo generates considerable amount of Bio waste which is generally degradable and this is collected from different enclosures and dumped in the garbage decomposition yard.
The converted compost is utilized as manure for the fodder bank and for regeneration and maintenance of lawns and trees. A team comprised of 4 people collects the garbage and is being transported by a tractor to the dump yard every day. The visitors are being screened at the entrance for plastics. The plastics are replaced with paper bags. The biodegradable and non-biodegradable wastes are separated and carefully dumped in the waste disposable decomposition yard. The decomposed manures are being used for enrichment of fodder bank and other planting works. All the waste recycled from Hippopotamus and Aviaries are properly utilized for irrigation purpose. Feed are carried in green plastic tub and wastes are carried away by red bins. The raised stainless steel feed and water troughs are being provided to all herbivores with roofed sheet to avoid contamination of food.
The 602 ha zoo is having priceless property and rare and endangered animals. The zoo security is mainly looked after by the Forest sub-ordinate staff comprising of Rangers, Foresters and Forest guards along with Zoo security staff.

Most of the animal houses of carnivores were constructed during 1985 required replacement due to the rusting of iron. The rusted gates and grills were causing injuries to the animals while scratching during the expression of territorial behaviour.
Hence the rusted iron gates and grills were replaced with stainless steel material to ensure safety and durability as directed by the Hon’ble Chief Minister and Chair person of Zoo Authority of Tamil Nadu. This is the first of its kind to be done in any zoo in the country.
